JAMES W. ANTHOINE, OF EUFAULA, ALABAMA.

CRUSHING AND GRINDENG MACi-HNE.

SPECIFICATION forming part of Letters Patent No. 319,166, dated June 2,1885.

Application filed July 3,1884. (No model.)

To all whom, it may concern.-

."Be it known that 1, JAMES W. ANTI-101N112, a citizenof the UnitedStates, residing at Eui'aula, in the county of Barbour and State ofAlabama, have invented certain new and useful Improvements in Crushingand Grinding Machines; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to lettersor figures of reference marked thereon, which form a part of thisspecification.

The present invention relates to the class of grinding-rolls in whichone roller rotates faster thanthe other; and the obj ect of my inventionis to provide a machine for crushing and disintegrating cottonseed andfeed for stock which shall be simple in construction and effective inits operation.

My invention,which consists of an improved machine especially designedfor the purpose stated, will be fully described, and then set forth inthe claim.

Figure l is a top view of the rolls with the hopper and feed-wheelremoved. Fig. 2 is a transverse section of one of the rollers, and Fig.3 is a vertical transverse section taken through the machine at one endof the grinding-rolls.

The frame A is of any approved construc- The rollers 13 and O are bothconical, placed with the cones reversed, so that the large end of onecomes opposite to the small end of the other, and their shafts aremounted in suitable bearings, b and c. The shaft of the roller Bisprovided at one end with a beltpulley, D, to receive a driving-belt fromany prime motor, and at the other with a small gear-wheel, E, whichmeshes in with a large gear-wheel, 13, on the shaft of the roller 0.This causes the roller B to rotate much faster than the roller 0,preferably in the ratio of about three to one. At one end of the shaftof the roller 0 there is asmall belt-pulley, G. which drives, throughthe medium of a belt, g, a large belt-pulley, h, on the shaft of thefeed-wheel H. The feed-wheel is a small cylinder studded with steelpins-h". It is journaled in the throat of the hopper and placed parallelwith the grinding-rolls and-the opening in 2,-which form cutting-edgesalong both sides of each groove. The cottonseed, feed for stock, orother material to be crushed having been delivered into the hopper, itis fed down to the rolls uniformly and evenly by the feedwheel H. Therollers have a twofold action on the cottonseed or other material onaccount of the difference in the speed of the two rollers. When plainsurfaces of the rolls are opposite to each other, the material caughtbetween them is subjected to a crushing and grinding action, due to thecompression of the material between the rolls and the attrition causedby one of the compressing-surfaces moving much faster than the other;but when a groove of one roller comes opposite to the plain surface ofthe other, or two grooves come opposite to each other, the difference inthe speed of the two rollers causes the edges of the grooves to cut andtear the material.

It will be seen that the relative surfacespeed of the rollers is not thesame at any two points, for the conical form of the rollers causes thesurface-speed of each roller to be fastest at the larger end and slowestat the small end, and the reversed position of the rolls brings theslowest-moving end of one opposite to the fastest end of the other,there being a middle point where the surface-speed of both rollers wouldbe the same but for this difference in the periods of revolution of thetwo rollers. The effect of the combination of these roller movementswith the cutting action of the furrows on cotton-seed or stock-feed isto cause a rapid disintegration of the same with a comparatively smallexpenditure of power. \Vhen the diagonal grooves are formedlongitudinally upon the surface of the rollers, and when one of the saidrollers is made to revolve more rapidly than the other, as hereinbeforefully described, the opposing surfaces of the two rollers at the pointwhere they meet successively consist of two plain faces, a plain faceand a groove, and two grooves. These opposing surfaces successivelysubject the material between them to the following actions: crushingonly, crushing and shearing, and shearing only, and thereby effect thecompletedisintegration of the material.

I am aware that grooved conical rolls driven at various speeds have beenused in grindingmills; that the grooves applied to such rollers havebeen formed under various systems; also, that hoppers and feedrollershave been used in connection with such mills. I therefore do not claimany of these features, broadly.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

A crushing and grinding machine comprising the conical rolls B and 0,having the diagonally-arranged grooves I formedupon their surfaces, thegear-wheels E and F,the drivingpulley D, the feedcylinder H, having itssurface studded with steel pins'h, and the pulleys g andh, for impartingmotion to the said feed= cylinder,substantially as described and shown,

and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.
